I know that they no longer make the 300ci manifolds or headers but does anyone know any other manifolds or headers that can fit i.e.-Headers from a 350 or something like that i have cracks in my manifolds and its giving me hell right now, that and does anyone have any tips or tricks on removing the old manifolds(rust) and whatnot? I have been using freeze-off to losen the bolts so far and was able to remove 2 with just a rarchet. Well any input would be great i just need something to work with because i really don't have $800.00 for custom headers. Thanks-Sean
